### Critical response

The season received mixed-to-positive reviews. Tanner Stransky of Cinema Blend gave a fresh review to the season, "Juxtaposed against that nightmare that launched season 8's 2-hour season premiere was exactly what the show does portray rather accurately (most of the time) - the relationship drama."
Verne Gay of Newsday acknowledged the following for the show stating, "Grey's has had a good season and has an intensely loyal fan base to prove it." TV Fanatic reviewing the episode Free Falling wrote, "This episode set the season in motion, and from the looks of it, it's going to be good."
Carrie Raisler of The A.V. Club gave a negative review to the season's alternate-reality episode, "Just because a show is meant to be fun doesn't mean it shouldn't have standards, and this episode just simply didn't measure up."
Poptimal'‍s Tanya Lane regarding the season finale wrote, "Wow…just wow. Grey's Anatomy has once again managed to shock with its season finale." While she appreciated the "realism and authenticity that Grey's is known for", she found the episode was "almost too much" as it was "extremely gory and difficult to watch, initially because of the grisly wounds" but later because of the "heavy and emotional things that transpired". She added that "Ellen Pompeo gave one of her best performances when her character learned that her sister was dead."
